  1. Find The Lost 3D Map Visualization & Path Finding sponsored by ASELSAN ~ ~ ~

  3. Adventurecontinues • What did we do? (briefly project topic) • How did we do? (methods / approaches) • What did we do with? (technologies) • What are we doing? (current state) • What will we do? (future work)

  4. Search & rescue teams • Their performance is vital! • They need: time, point and direction to go. • They need to be encouraged, helped. • FTL will help them.

  5. Whatdidwe do? • 3D map • Paths on land • Countless different paths • Fastest path • Depends on vehicle & weather • Paths for also air • …

  11. How did we do? • Algorithm Component • Vector map of DTED • Dijkstra algorithm (modified for “fastest path”) • Map Visualization • Android Interface

  12. Digitalterrainelevation data

  13. Vectormap (targetarea)

  14. Vectormap (fastestpath)

  15. Vectormap (fastestpath)

  16. Dijkstra algorithm (modified) 1235 m …finds “shortest” path Side view of map height Path length 1212 m 30 m • …finds “fastest” path • Path time = Path length/(velocity of vehicle depending on height)

  27. What did we do with? • Eclipse • Java • Android 2.1 • OpenGL ES • Tablet • Smart phone • Android emulator

  28. What are we doing? • Algorithm component is totally finished • Map visualization • User Interface are partially finished. • Touch movement actions • Integration completed }

  29. What are we doing? • We have contacted with AKUT at Isparta. • They have visited our stand at Süleyman Demirel University Project Competition. • We have exchanged ideas about usability of FTL. Moreover, our project was awarded 2nd place in 55 different projects.

  30. What are we doing?

  31. What are we doing?

  32. What will we do? • Bugfixes • Preventing memory overflow • Proper working of movement actions • Bluetooth connection between tablet and smart phone • Texture mapping of satellite photos over 3D map • Improving performance of algorithms • Enlarging map if Android allows • Path for helicopter
